Hi there, I’m Elizabeth, a board-certified Psychiatric Mental Health Nurse Practitioner with more than five years of experience supporting adults 18 and older. I went into psychiatry because I saw how deeply mental health and overall health are connected, and I knew I wanted to make a meaningful difference in people’s lives. I’m honored to walk alongside my clients as they move toward healing, growth, and greater wellness.
With over a decade of experience in the healthcare field, I bring a strong foundation of clinical expertise and compassionate care. For eight years, I worked as a Med-Surg nurse, travel nurse, and cardiac nurse, gaining diverse experience across high-acuity settings and patient populations. The variety of roles allowed me to develop adaptability, resilience, and a deep understanding of both acute and chronic health conditions. It also allowed me to see the role mental health plays and the importance it holds.
For the past two years, I have been practicing as a Psychiatric Mental Health Nurse Practitioner (PMHNP), where I’ve focused on providing holistic, patient-centered care that addresses both mental and physical health.
This blend of medical-surgical and psychiatric experience equips me with a comprehensive perspective on patient care, allowing me to treat the whole person—not just the diagnosis.
Welcome
Hello, and thank you for considering me as your therapist. My name is Tarianda Ruston, and I have more than 25 years of experience working in the helping profession. I am a licensed clinical social worker in both Maryland and the District of Columbia, with a diverse background that has allowed me to support individuals and families through many of life's challenges.
Throughout my career, I have worked in child welfare, foster care and adoption, inpatient mental health, custody cases, special education, and school mental health. These experiences have provided me with a deep understanding of the unique challenges people face across different stages of life. My passion is helping individuals discover their strengths, overcome obstacles, and build the tools needed for lifelong emotional wellness.
I believe therapy is a partnership built on trust, respect, and authenticity. My role is not to tell you what to do or make decisions for you. Instead, I provide a safe, supportive, and nonjudgmental space where you can explore your thoughts, emotions, and experiences openly. Through thoughtful questions, compassionate reflection, and evidence-based strategies, I will help you gain insight, clarify your values, and make choices that align with the life you want to create.
I am licensed clinical professional counselor with over 30 years experience in Human Services. I am CEO of Metanoia Mental Health LLC a former graduate of Loyola university with master's degrees in pastoral counseling as well as mental health.
